Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present patent application claims benefit and priority to Chinese Application No. 2020109073268 filed on Aug. 31, 2020 which is hereby incorporated by reference into the present disclosure.

TECHNICAL FIELD

The present disclosure relates to the technical field of sterilization lamp equipment, in particular to an ultraviolet sterilization line lamp.

BACKGROUND

Commonly, the ultraviolet lamp tube of the ultraviolet lamp is open, which causes the ultraviolet light to directly irradiate the entire environment to be sterilized when the ultraviolet lamp is working. Since ultraviolet rays are very harmful to the human body, when there are people in the environment, in order to avoid damage to the human body, it is necessary to stop using the ultraviolet lamp, which makes it impossible to use the ultraviolet lamp for environmental sterilization.

Ultraviolet lamp has a good sterilization effect, but it usually requires people to leave the sterilization place, otherwise it will cause harm to people. To ensure human safety, a human body induction control device can be designed on the UV lamp to ensure that the UV lamp stops working when someone is present; the ultraviolet lamp can also be provided in the sealing cavity, and air is sucked into the sealing cavity through the fan module, and then discharged after being sterilized by the ultraviolet lamp to complete the sterilization. The safety of the former scheme depends on the accuracy and stability of the induction control device, and when there are people in the sterilization place for a long time, it is difficult for the ultraviolet lamp to turn on the sterilization mode, which affects the use. The latter solution requires air to be sucked into the sealing cavity through the fan module to kill the virus, the sterilization effect is related to the power of the fan module and the air circulation capacity, and the energy consumption is high, and it is prone to generate louder noise. Besides, since ultraviolet rays cannot be directly irradiated to open sterilization places, the sterilization effect is much worse than when ultraviolet rays are directly exposed and used in sterilization places.

In an embodiment of the present disclosure, as shown in FIG. 1 to FIG. 6, the ultraviolet sterilization line lamp includes a lamp body 1, two grilles 2 and two ultraviolet sterilization modules 3. The lamp body 1 is elongated, and two sides of the lamp body 1 are provided with two accommodating grooves 11. The two grilles 2 are connected to the lamp body 1 and respectively located in the two accommodating grooves 11. Inner wall surfaces of each of the grilles 2 and each of the accommodating grooves 11 form a sterilization cavity 13, each of the grilles 2 includes light exit grooves 21 communicating with the sterilization cavity 13, each of the light exit grooves 21 extends from one end of a corresponding grille 2 close to the lamp body 1 to another end of the corresponding grille 2 away from the lamp body 1, an inner wall surface of each of the light exit grooves 21 is provided with a light-absorbing layer; and the two ultraviolet sterilization modules 3 are connected to the lamp body 1 or the grille 2, and respectively located in two sterilization cavities 13.

It should be understood that a length direction of the lamp body 1 is a front-rear direction of the lamp body 1, a direction of the lamp body 1 to the grilles 2 on both sides is a left-right direction, and a direction of the lamp body 1 away from the ground to close to the ground is an up-down direction. The two grilles 2 are provided at the left direction and right direction of the lamp body 1, respectively.

In this embodiment, the two grilles 2 are provided on opposite sides of the lamp body 1, and the ultraviolet sterilization module 3 is provided between the lamp body 1 and the grille 2, such that the ultraviolet rays generated by the ultraviolet sterilization module 3 are emitted from the grille 2 on both sides of the lamp body 1. The ultraviolet sterilization line lamps are usually hoisted or directly installed on the ceiling. Ultraviolet rays are emitted from the grille 2 on both sides of the lamp body 1 to prevent ultraviolet rays from irradiating the human body and improve the safety of the ultraviolet sterilization line lamp. In addition, one end of the light exit groove 21 of the grille 2 is away from the lamp body 1, so that ultraviolet rays can be directly emitted into the environment outside the lamp, and the sterilization effect of the air in the surrounding environment of the grille 2 is improved. Ultraviolet rays are directly emitted towards the areas corresponding to the two grilles 2 to increase the sterilization range of ultraviolet rays on the air in the environment. Meanwhile, under the action of air convection, the sterilized air can be discharged as soon as possible and the unsterilized air can enter the sterilization area directly exposed to ultraviolet rays as soon as possible, thereby improving the sterilization efficiency of the overall space. Even without a fan, a good sterilization effect can be obtained. On the other hand, the light exit grooves 21 are provided on the grille 2, and the light exit grooves 21 extend from one end of the grille 2 close to the lamp body 1 to the other end of the grille 2 away from the lamp body 1. In other words, the light exit groove 21 of the grille 2 has a longer covering length, and the surface of the light exit groove 21 is provided with a light-absorbing layer that absorbs ultraviolet rays. When the ultraviolet rays are irradiated in the direction of the grille 2, except for the ultraviolet rays parallel to the inner wall surface of the light exit groove 21 can be emitted from the lamp, other ultraviolet rays will be absorbed by the inner wall surface of the light exit groove 21, reducing the probability of ultraviolet rays directly irradiating the human body, and enhancing the safety of the ultraviolet sterilization line lamp. The ultraviolet sterilization line lamp of the present disclosure improves the safety of environmental sterilization by ultraviolet rays and improves the sterilization effect.

In an embodiment, the light exit groove 21 of the grille 2 emits ultraviolet rays horizontally, obliquely upward, or vertically upward, which can achieve the effect of safe use.

In an embodiment, the accommodating groove 11 is configured as a reflective surface. It should be understood that a mirror layer is provided on the inner wall surface of the accommodating groove 11. Or, the inner wall surface of the accommodating groove 11 is coated with a reflective coating. Or, a reflective film is pasted on the inner wall surface of the accommodating groove 11. Or, the inner wall surface of the accommodating groove is polished to form a reflective surface.

In the application of this embodiment, the ultraviolet sterilization module 3 can have two settings. The ultraviolet sterilization module 3 can adopt a scheme of an ultraviolet lamp tube to emit light; or, the ultraviolet sterilization module 3 can adopt a scheme of a LED ultraviolet lamp bead to emit light, as follows:

When the ultraviolet sterilization module 3 can adopt the scheme of ultraviolet lamp tube to emit light, the ultraviolet lamp tube can be installed on the lamp body 1 or the grille 2, and the ultraviolet lamp tube corresponds to the light exit grooves 21. In order to improve the light utilization rate of the ultraviolet lamp tube, a reflective surface structure may be provided on the inner wall surface of the accommodating groove 11, such that the light of the ultraviolet lamp tube can be reflected by the reflective surface structure and then transmitted from the light exit groove 21, which improves the energy utilization rate and enhances the sterilization effect.

When the ultraviolet sterilization module 3 can adopt the scheme of LED ultraviolet lamp bead to emit light, the LED ultraviolet lamp bead can be installed on the lamp body or the grille 2 so that the LED ultraviolet lamp bead corresponds to the light exit groove 21. When the LED ultraviolet lamp bead is installed on the lamp body 1, the LED ultraviolet lamp bead is facing the light exit groove 21; when the LED ultraviolet lamp bead is installed on the grille 2, the LED ultraviolet lamp bead can be partially extended into the light exit groove 21.

In an embodiment of the present disclosure, the lamp body 1 can have various implementation forms. For example, the accommodating grooves 11 on both sides of the lamp body 1 are sink grooves or open grooves. Take the following two cases as examples:

In the first case, the accommodating grooves 11 on both sides of the lamp body 1 may be sink grooves; that is, sink grooves are provided in the left-right direction of the lamp body 1. That is to say, the two grilles 2 can be at least partially embedded in the containing groove 11.

In the second case, the accommodating grooves 11 on both sides of the lamp body 1 may be open grooves; that is, open grooves are provided in the left-right direction of the lamp body 1. That is to say, two sides of the lamp body 1 extend to form bosses on both sides of the lamp body 1, and the bosses on both sides of the lamp body 1 cooperate with the lamp body 1 to form open grooves. It can be considered that the boss is provided below the grille 2.

In the application of the above-mentioned embodiment, the grille 2 and the lamp body 1 can be assembled by snap connection, plug-in fitting, screw locking, and the like. Understandably, the boss can be used to support the grille 2; on the other hand, the boss can also shield the ultraviolet grille 2 to prevent ultraviolet rays from being emitted from the gap between the grille 2 and the lamp body 1.

In an embodiment of the present disclosure, as shown in FIG. 1, the ultraviolet sterilization line lamp further includes a mounting portion 17. Understandably, a mounting position may be provided on the lamp body 1, and the mounting portion 17 is limited to a mounting position. The mounting portion 17 is connected to the lamp body 1. Taking the mounting portion 17 as a connection piece, an end of the mounting portion 17 away from the lamp body 1 can be connected to the ceiling. The hoisting clamp can usually be connected to a rope, and the other end of the rope is connected to the ceiling. Or, the hoisting clamp can also be a long rod, and the rod is directly connected to the ceiling.

In an embodiment, the mounting position can be a chute, a threaded hole or a pin hole, etc. Taking the mounting position as a chute as an example, the chute can be provided along the length of the lamp body 1, and a notch of the chute is provided as a narrowing. The mounting portion 17 is a hoisting clamp, which is clamped in the chute and can move along the chute.

In an embodiment of the present disclosure, as shown in FIG. 3, FIG. 5 and FIG. 6, each of the light exit grooves 21 extends from one end of the grille 2 close to the lamp body 1 to the other end of the grille 2 away from the lamp body 1. It can be considered that each of the light exit grooves is centered on the lamp body 1 and extends in the left-right direction of the lamp body 1.

In the application of the above-mentioned embodiments, as shown in FIG. 1, taking a central symmetry plane of the lamp body 1 as a reference plane 19, the two accommodating grooves 11 are mirror images of the reference plane 19. In other words, the central symmetry plane of the lamp body 1 is a vertical plane perpendicular to the ground, and the vertical plane is provided along the length direction of the lamp body 1. Taking the direction perpendicular to the reference plane 19 as the horizontal direction, the light exit groove 21 may be parallel to the horizontal direction; or, the light exit groove 21 may form an angle with the horizontal direction.

In an embodiment of the present disclosure, the light exit groove 21 may form an angle with the horizontal direction. The extending direction of the light exit groove 21 away from the notch of the lamp body 1 is an oblique upward direction. When the ultraviolet rays are emitted from the light exit groove 21, the ultraviolet rays can be emitted upwards to prevent the ultraviolet rays from being emitted to the user.

In an embodiment of the present disclosure, as shown in FIG. 3, FIG. 5 and FIG. 6, each of the grilles 2 includes light-absorbing plates 22 provided in the left-right direction; or, provided in the up-down direction.

On one hand, as shown in FIG. 3, FIG. 5 and FIG. 6, the light-absorbing plates 22 are provided in the left-right direction, which means that each of the light-absorbing plates 22 is provided along a length direction of the lamp body 1, and an extension surface of each of the light-absorbing plates 22 is perpendicular to the reference plane 19, and two adjacent light-absorbing plates 22 are spaced apart and form a light exit groove 21. The length direction is the front-rear direction of the lamp body 1.

On the other hand, the light-absorbing plates 22 are provided in the up-down direction, which means that each of the light-absorbing plates 22 is provided along a thickness direction of the lamp body 1, and an extension surface of each of the light-absorbing plates 22 is perpendicular to the reference plane 19, and two adjacent light-absorbing plates 22 are spaced apart and form a light exit groove 21. The thickness direction is the up-down direction of the lamp body 1.

In an embodiment of the present disclosure, taking a central symmetry plane of the lamp body 1 as a reference plane 19, the two accommodating grooves 11 are mirror images of the reference plane 19.

Each of the grilles 2 includes light-absorbing plates 22 along a length of the lamp body 1, an extension surface of each of the light-absorbing plates 22 is perpendicular to the reference plane 19, two adjacent light-absorbing plates 22 are spaced apart and configured to form the light exit groove 21; a surface of each of the light-absorbing plates 22 is provided with the light-absorbing layer; and each of the two accommodating grooves 11 is configured as a reflective surface.

In this embodiment, the extension surface of each of the light-absorbing plates 22 is perpendicular to the reference surface 19 to form the light exit grooves 21 perpendicular to the reference surface 19. When the ultraviolet sterilization module 3 emits ultraviolet rays, the ultraviolet rays can be emitted out of the grille 2 in parallel to sterilize the air in the parallel direction of the grille 2. As for the space below the grille 2, ultraviolet rays cannot be directly irradiated to the bottom, and the ultraviolet rays are prevented from directly irradiating the space below, which can ensure the safety of users in the space below. On the other hand, the accommodating groove is configured as the reflective surface, such that the intensity of the ultraviolet rays emitted from the grille can be higher, and the utilization rate of the ultraviolet rays can be improved.

In an embodiment of the present disclosure, the light-absorbing layer may be a coating coated on the surface of the light-absorbing plate 22; or, the light-absorbing layer may be a structure in which metal is deposited on the surface of the light-absorbing plate 22; or, the light-absorbing layer may be a diffuse reflection layer formed by physical polishing.

In an embodiment of the present disclosure, as shown in FIG. 3, each of the light-absorbing plates 22 is provided with a bending portion 23 at one end adjacent to a corresponding ultraviolet sterilization module 3. That is to say, one end of the light-absorbing plate 22 adjacent to the ultraviolet sterilization module 3 is bent to form the bending portion 23, so that one end of the light exit groove 21 formed by two adjacent light-absorbing plates 22 is a bending groove body. After the ultraviolet sterilization module 3 emits ultraviolet rays, the ultraviolet rays are partially blocked by the bending portion 23 of the light-absorbing plate 22, which reduces the intensity of the ultraviolet rays emitted to the outside, thereby improving the safety of the ultraviolet sterilization line lamp.

In an embodiment of the present disclosure, as shown in FIG. 4, FIG. 7 and FIG. 8, the lamp body 1 is further provided with a through hole 12 communication with the two accommodating grooves 11; and the ultraviolet sterilization line lamp further includes a fan module 6 provided on the lamp body 1 and located at the through hole 12, to enhance the air flow through the lamp body 1, thereby enhancing the sterilization effect.

That is, the mounting bracket 61 abuts or clamps with the inner wall surface of the first frame 14 through the clamping portion 613, avoiding the use of screws between the mounting bracket 61 and the lamp body 1, which can improve the efficiency of disassembly and assembly.

In an embodiment, the clamping portion 613 may be a protrusion, and the protrusion abuts against the inner wall surface of the limiting space 121 to hold the mounting bracket 61 on the lamp body 1.

In an embodiment, the clamping portion 613 includes two protrusions, the two protrusions form a limiting gap, and the peripheral wall surface of the through hole 12 is limited within the limiting gap.

In an embodiment, the clamping portion 613 includes protrusions spaced apart. The protrusions are accommodated in the limiting space 121 and abut against the inner wall surface of the limiting space 121 to position the mounting bracket 61 on the lamp body 1.

The mounting bracket 61 is pushed into the through hole 12 of the first frame 14 as a whole. When the user removes the force acting on the second plate 612, the second plate 612 returns to the original state relative to the first plate 611, such that the clamping portion 21 is snap-fitted with the escape space 616 of the inner wall surface of the through hole 12, and the mounting bracket 61 is connected to the first frame 14.
